Abstract : Architecture of a Ring communication network based on the Distributed Computing System (DCS) at the University of California, Irvine is presented. Control of the network is distributed in time among the active processors for reliability. A pseudo-bipolar violation protocol, modeled after the Farmer and Newhall ring at Bell Labs, is used to implement synchronization, control passing, and variable length messages. The prototype system is designed to make extensive use of micro-computers for flexibility in design. Ring organization and protocol are discussed with the major emphasis on the use of an INTEL MCS-8 Micro-Computer at the interface of a teletype to the ring. The MCS-8 program is written in PL/M-a higher level language for INTEL's micro-computers. (Author)
